R21xx-HP FlexFabric 11900 Network Management and Monitoring Command Reference

6
-t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The timeout argument is
in the range of 0 to 65535. The default value is 2000.
-v: Displays detailed information (including the dst field and the idx field) about ICMPv6 echo replies. If
this keyword is not specified, the system only displays brief information (not including the dst field and the
idx field) about ICMPv6 echo replies.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. If the destination is on the public network, do not specify this option.
-i interface-type interface-number: Specifies an outbound interface by its type and number. This option
must be specified when the destination address is a multicast address or a link local address. If this
option is not specified, the ICMP echo request sending interface is determined by searching the routing
table or forwarding table according to the destination IP address.
host: Specifies the IPv6 address or host name (a string of 1 to 253 characters) for the destination.
Usage guidelines
To use the name of the destination host to perform the ipv6 ping operation, you must first configure DNS
on the device. Otherwise, the ipv6 ping operation fails.
To abort the ping ipv6 operation during the execution of the command, press Ctrl+C.
